In a large slow cooker, whisk together broth, vinegar, honey, soy sauce, mustard and garlic. Place roast in the centre, scoop a few spoonfuls of the sauce on top and cover. Cook on Low for 8 – 10 hours or on High for 4 – 5 hours.

When meat is cooked, open the lid and using 2 forks shred the roast directly in the slow cooker or on a cutting board. Stir together with the sauce. Serve hot with real mashed potatoes, faux cauliflower “mashed potatoes” or on whole wheat buns.
